SELF-CLEARING FURNACE-GRATE.
SPECIFICATION forming part of Letters Patent No. 292,230, dated January 22, 1884, 1
Application filed May 8, 1 883. (No model.)
2" MA w/wm it may concern:
Be it known that I, JAMES C. J ONES, of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Self-Clearing Furnace- Grates; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification.
My invention relates to that class of grates in which rocking grate-bars are used; and the invention consists in pivoting or journaling the bars in different planes, so that when the bars are moved or rockedthey shall have a differential movement, whereby some of the bars shall be made to move in the arc of a larger circle than others, thus moving a greater distance and varying the spaces between them and the other bars, all as'hereinafter more fully set forth.
Figure 1- is a side elevation of a grate embodying my invention. Fig. 2 is a similar view,with a portion of the frame broken away; and Fig. 3 is a top plan view of the same.
Grates have long been made with their bars arranged to rock or oscillate in Various ways 5 but, so far as I am aware, in all such cases the movable bars have been arranged so as to have a uniform movementthat is to say, the bars all moved the same dista cc and retained the same relative position to each other. My invention differs from all such in that the bars are so arranged that when they are simultaneously moved a portion of them will oscillate or rock through the arc of a larger circle than the others, thus moving a greater distance, and vary the width or spaces between them and the adjoining bars.
In the drawings, Dindicates the grate-bars,
which are provided with journals at their,
ends, so they can be pivoted in a suitable frame or supports in such a manner as to freely rock to and fro. These bars are provided along their upper surfaces with a series of projections, of any suitable form for supporting the coal and crushing or breaking up the clinker, and each having avertically-depending arm, by which they are all connected to a rod or bar, B, by which they can be simultaneously moved or shak'en, as is usual in this the device as a whole can be set in the fire-.
chamber, or the bars may be simply journaled in two side bars securedin the chamber, as preferred. These bars, instead of having their journals located at a .uniform distance from their top or upper surface, are made in two series or sets, one set having their journals locatedconsiderably farther from the top of the bar than are those of the other set, as indicated in Fig. 1, in which A indicates the journals of one set, and A the journals of the other set of bars. In mounting these bars in their frame, I so arrange them that their upper surfaces shall all be in the same horizontal plane, or substantially so, and consequently the holes or bearings for their journals will be arranged in two different planes, one higher than the other, as represented in Figs. 1 and- 2. The result of this construction and arrangement is that those bars which have their journals placed in the lower plane will move through the arc of a much larger circle than the others, and will consequently move much farther. By this increased movement these bars will swing away from the adjoining bar on one side over toward the adjoining bar on its opposite side when moved in one direction, and will reverse the operation when moved in the opposite direction, thus oscillating or moving to and fro between the adjoining bars. This movement raises the clinker, coal, and ashes, breaking up the former and sifting out the latter, and the increased or enlarged spaces thus formed at intervals afford increased facility for the escape of both ashes and clinker.
I have shown the bars of thetwo sets'arranged alternately in regular order; but it is obvious that this order may be varied without departing from the spirit of my invention, the gist of which is in so arranging or pivoting the barsas to impart to them a differential-move ment, as described. The horizontal bar B is arranged to project at the front, and is connected to a pivoted lever, by which all the bars are movedsimultaneously, and more or less, as may be desired. It will be observed that by this peculiar method of pivoting bars in different planes those which have the greater movement will drop below the others as they approach the extremity of their movement in either direction, thus causing them to rise and fall more than the intervening bars, thus tending to lift and break up any crust or sheet of clinker that may form in the fire.
- This movement also tends to shake up the jecting stud or wrist, which engages in holes in t the bar 13, and in such case it is only necesthe l sary to elongate vertically those holes in which the studs of the lower journaled bars engage.
Having thus described my invention, what I claim is- 1. A grate composed of a series of rocking bars, a portion of which shall be pivoted in a horizontal plane, while the remaining portion shall be pivoted in another and different plane parallel with the first, substantially as shown and described.
2. A grate composed of a series of bars, a portion of which shall have a differential movement in relation to the other bars of the series, substantially as and for the purpose set forth, whereby some of the bars shall be made to move in the arc of a larger circle than the others.
